Dabi had received a simple mission, or so it seemed. Shigaraki had tasked him with finding out more about this villain in the upper parts of Japan, but the other villains and people were all hush hush up there. All wary, so he took it into his own hands and somewhat kidnapped a henchmen and tortured him for mission. The henchmen gave a name but that was it, despite the new burns that scattered his arms. But dabi was sure he fucked up, after a few days of silence from the other villains.
A simple sleeping dart shot from afar and the scarred villain was transferred to a plain white rubber room. Isolated for about a two months, yes they gave him food and a place to sleep but besides that. No human contact what so ever, being cuffed up and isolated for a long time had left some mental scars. But dabi could handle it, couldn't he?
